Description
Die Erfindung betrifft ein Geschirrspülmittel zur maschinellen Reinigung von Geschirr.The invention relates to a dishwasher detergent for machine washing Cleaning of dishes.
Zum Geschirrspülen in Geschirrspülautomaten mit Dosiergeräten ist es bekannt, flüssige Geschirrspülmittel einzusetzen, deren Zusammensetzung auch eine Bleichmittelkomponente beinhaltet.For washing dishes in automatic dishwashers with dosing devices it is known to use liquid dishwashing detergents, the composition of which also contains a bleach component includes.
Die bekannten Bleichmittel auf Chlorbasis, insbesondere Natriumhypochlorit, weisen eine Reihe von Nachteilen auf. So ist beispielsweise Natriumhypochlorit in wäßrigen Lösungen (pH-Wert kleiner als 9,5) nicht sehr stabil und verliert seine wirksame Bleichkraft beim Lagern. Außerdem sinkt die Bleichwirkung von Natriumhypochlorit-haltigen Bleichmittellösungen mit steigendem pH-Wert und niedriger Temperatur. Andere Bleichmittel mit aktivem Chlor, wie beispielsweise die chlorierten Isocyanursäuren sind zwar stabiler als Natriumhypochlorit, führen aber zur Korrosionsbildung.The known chlorine-based bleaches, especially sodium hypochlorite, have a number of disadvantages. So is, for example, sodium hypochlorite in aqueous solutions (pH less than 9.5) not very stable and loses its effective bleaching power when stored. It also drops Bleaching effect of sodium hypochlorite-containing bleach solutions with increasing pH and low temperature. Other active chlorine bleaches, such as the chlorinated isocyanuric acids are more stable than sodium hypochlorite, but lead to the formation of corrosion.
Ein wesentlicher Nachteil besteht darin, daß chlorhaltige Produkte aufgrund ihrer ökologischen Unverträglichkeit als stark belastend einzustufen sind. In der Umwelt schädigt freigesetztes Chlor als Gas oder in Lösung die Pflanzen- und Tierwelt. Beim Menschen verursacht das freigesetzte Chlor Reizungen und Ätzungen der Atmungsorgane.A major disadvantage is that chlorine Products because of their ecological intolerance are classified as extremely stressful. Harms in the environment released chlorine as gas or in solution and wildlife. This causes the release in humans Chlorine Irritation and corrosion of the respiratory system.
Es sind deshalb schon andere Bleichmittel vorgeschlagen worden, um die vorgenannten Probleme, insbesondere hinsichtlich der aggressiven und umweltschädigenden Eigenschaften von Aktivchlor, zu überwinden. So sind beispielsweise aus US 45 68 476 oder EP 01 95 619 A2 Peroxoverbindungen für Geschirrspülmittel bekannt, die unter Freisetzung von Aktivsauerstoff arbeiten. Ein erheblicher Nachteil dieser Bleichmittel besteht jedoch in der katalytischen Zersetzung des aus den Peroxoverbindungen entstehenden Wasserstoffperoxids durch Eisen, Kupfer und andere Schwermetalle sowohl als Ionen als auch als feste Metalle. Da bereits geringste Spuren der metallischen Störkatalysatoren zersetzend wirken, treten bereits bei der Lagerung von Peroxidlösungen Konzentrationsverluste ein. Neben diesen Schwermetallen ergeben Untersuchungen mit Wasserstoffperoxid auch eine Verminderung der Stabilität sowohl bei der Erniedrigung als auch bei der Erhöhung des pH-Wertes.Other bleaching agents have therefore been proposed to the aforementioned problems, especially regarding the aggressive and environmentally harmful properties of active chlorine to overcome. For example, are out US 45 68 476 or EP 01 95 619 A2 peroxo compounds for dishwashing detergents known to release active oxygen work. A major disadvantage of these bleaches however, consists in the catalytic decomposition of the hydrogen peroxide formed from the peroxo compounds by iron, copper and other heavy metals as well Ions as well as solid metals. Even the slightest trace of metallic catalytic converters have a decomposing effect, Concentration losses already occur during the storage of peroxide solutions a. In addition to these heavy metals Investigations with hydrogen peroxide also decrease of stability in both humiliation as well when increasing the pH.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Geschirrspülmittel zu schaffen, das keine aggressiven und umweltschädigenden Eigenschaften aufweist und das in Gegenwart von Schwermetallen und in üblichen pH-Bereichen alkalischer Geschirrspülmittel auch bei pH-Werten über 12,5 seine volle Wirksamkeit behält. The invention is therefore based on the object of a dishwashing detergent to create that no aggressive and environmentally harmful Has properties and that in the presence of heavy metals and more alkaline in common pH ranges Dishwashing detergent even at pH values above 12.5 retains full effectiveness.
Diese Aufgabe wird mit einem Geschirrspülmittel enthaltend:This task is accomplished with a dishwashing detergent:
15-18 Gew.-% Kaliumtriphosphat (50%) eisenarm,
19-21 Gew.-% Kalilauge (45%),
9-11 Gew.-% Natriumwasserglas,
0,5-1,5 Gew.-% Wasserstoffperoxid (30%),
0,5-1,5 Gew.-% Magnesiumsulfat-Heptahydrat
(MgSO₄×7 H₂O) oder
0,5-1,5 Gew.-% Magnesiumsulfat-Haptahydrat/Borax und
ad 100 Gew.-% Wasser15-18% by weight potassium triphosphate (50%) low in iron,
19-21% by weight potassium hydroxide solution (45%),
9-11% by weight sodium water glass,
0.5-1.5% by weight hydrogen peroxide (30%),
0.5-1.5 wt .-% magnesium sulfate heptahydrate (MgSO₄ × 7 H₂O) or
0.5-1.5% by weight magnesium sulfate haptahydrate / borax and
ad 100 wt .-% water
gelöst. solved.
Es wurde überraschend gefunden, daß diese Zusammensetzung ein Geschirrspülmittel liefert, das dieselben spültechnischen Eigenschaften wie bisher verwendete chlorhaltige Geschirreiniger besitzt, d. h. Anschmutzungen am Geschirr, wie angetrockneter Kaffee oder Eigelb, werden problemlos von der Spülgutoberfläche entfernt, ohne daß das Spülmittel aggressive und umweltgefährdende Substanzen aufweist. Dabei werden bekannte Wasserstoffperoxide als Bleichmittel verwendet, die jedoch erst durch den Einsatz von Magnesiumsulfat- Heptahydrat als Stabilisierungsmittel zu einem stabilen Bleichmittel führen, das nicht durch Schwermetalle oder pH- Wertveränderungen destabilisiert wird.It has surprisingly been found that this composition provides a dishwashing detergent that does the same Properties as previously used chlorine dishwashers owns, d. H. Soiling on the dishes, such as dried coffee or egg yolk, are easily from removed from the washware surface without detergent aggressive and environmentally hazardous substances. Here known hydrogen peroxides are used as bleaching agents, which, however, is only possible through the use of magnesium sulfate Heptahydrate as a stabilizing agent to a stable Bleach that is not caused by heavy metals or pH Changes in value are destabilized.
Als besonders geeignet hat sich eine Zusammensetzung erwiesen, die aus 16,6 Gew.-% Kaliumtriphosphat (50%) eisenarm, 20 Gew.-% Kalilauge (45%), 10 Gew.-% Natriumwasserglas, 1 Gew.-% Wasserstoffperoxid (30%), 1 Gew.-% Magnesiumsulfat- Heptahydrat und 51,4 Gew.-% Wasser besteht. Dieses Geschirrspülmittel liefert sehr gute Spülergebnisse und ist genauso wirksam, wie die bisher bekannten chlorhaltigen Geschirreiniger, ohne deren Nachteile aufzuweisen.A composition has proven to be particularly suitable which consists of 16.6% by weight potassium triphosphate (50%) low in iron, 20% by weight potassium hydroxide solution (45%), 10% by weight sodium water glass, 1% by weight hydrogen peroxide (30%), 1% by weight magnesium sulfate Heptahydrate and 51.4 wt .-% water. This dishwashing liquid delivers very good washing results and is just as effective as the previously known chlorine dishwashers, without showing their disadvantages.
Durch den Zusatz von Magnesiumsulfat-Heptahydrat entsteht eine stabilisierende Wirkung, da sich Magnesiumhydroxid (Mg(OH)₂) in der Lösung bildet, das teilweise als weißer Niederschlag ausfällt. Zur Vermeidung von Verstopfungen der Ventile oder dgl. in der Spülmaschine ist deshalb vorgesehen, daß das Geschirrspülmittel nach der Zubereitung filtriert wird. Auch nach der Abtrennung des nicht in Lösung gegangenen Magnesiumhydroxids bleibt die Lösung beständig, das gelöste Magnesiumhydroxid fällt die Schwermetallkatalysatoren nicht nur weitestgehend aus und beseitigt diese, sondern vermag auch eine Einwirkung auf das Wasserstoffperoxid abzuschirmen.The addition of magnesium sulfate heptahydrate creates a stabilizing effect because of magnesium hydroxide (Mg (OH) ₂) forms in the solution, sometimes as a white Precipitation fails. To avoid constipation of the Valves or the like in the dishwasher is therefore provided that the dishwashing liquid is filtered after preparation becomes. Even after separating the not in solution gone magnesium hydroxide, the solution remains stable, The dissolved magnesium hydroxide falls off the heavy metal catalysts not only largely and eliminates them, but can also act on the hydrogen peroxide shield.
Die Erfindung ist nachstehend anhand eines Ausführungsbeispieles erläutert, ohne auf dieses Ausführungsbeispiel beschränkt zu sein:The invention is based on an exemplary embodiment explained without being limited to this embodiment to be:
Erfindungsgemäß wurde ein Geschirrspülmittel mit folgender Zusammensetzung zubereitet:According to the invention, a dishwashing detergent with the following Prepared composition:
16,6 Gew.-% Kaliumtriphosphat (50%) eisenarm
20 Gew.-% Kalilauge (45%),
10 Gew.-% Natriumwasserglas,
1 Gew.-% Wasserstoffperoxid (30%),
1 Gew.-% MgSO₄×7 H₂O und
51,4 Gew.-% H₂O.16.6% by weight potassium triphosphate (50%) low in iron
20% by weight potassium hydroxide solution (45%),
10% by weight sodium water glass,
1% by weight hydrogen peroxide (30%),
1 wt .-% MgSO₄ × 7 H₂O and
51.4% by weight H₂O.
Die entstandene Lösung wurde anschließend abfiltriert, da der Hydroxid-Niederschlag in den Dosiergeräten einer Geschirrspülmaschine Ventile zusetzen könnte. Diese Rezeptur zeigte in Laborversuchen sehr gute Reinigungswirkungen in Bezug auf Kaffee, Tee, Lippenstift und Eigelb.The resulting solution was then filtered off because the hydroxide precipitation in the dosing devices of a dishwasher Valves could clog. This recipe showed very good cleaning effects in laboratory tests Regarding coffee, tea, lipstick and egg yolk.
Anschleßend wurde das Geschirrspülmittel nach der vorgenannten Rezeptur in einer gewerblichen Geschirrspülmaschine einer Großküche eingesetzt. 24 Stunden lang wurde das gesamte anfallende Spülgut mit dem betreffenden Geschirrspülmittel gespült. Es wurde festgestellt, daß dieses Reinigungsmittel dieselben spültechnischen Eigenschaften wie bisherige chlorhaltige Geschirreiniger besitzt, d. h., farbige Anschmutzungen, wie angetrockneter Kaffee oder Eigelb wurden problemlos von der Spülgutoberfläche entfernt. Zwar ist gegenüber chlorhaltigen Spülmitteln eine etwas höhere Dosierung erforderlich, dies ist jedoch in der weniger aggressiven Wirkung des Sauerstoffes im Vergleich zum Chlor begründet. The dishwashing detergent was then made according to the aforementioned Recipe in a commercial dishwasher used in a commercial kitchen. For 24 hours, the whole wash ware with the relevant dishwashing detergent rinsed. It has been found that this detergent the same washing properties as previous ones has chlorine-based dishwashers, d. h., colored stains, like dried coffee or egg yolk easily removed from the washware surface. Although is opposite chlorine-containing detergents a slightly higher dosage required, however, this is in the less aggressive Effect of oxygen compared to chlorine justified.
Natürlich ist die Erfindung nicht auf das dargestellte Ausführungsbeispiel beschränkt. Weitere Ausgestaltungen der Erfindung sind möglich, ohne den Grundgedanken zu verlassen. Wesentlich ist jedoch, daß das Geschirrspülmittel erfindungsgemäß stabilisiertes Wasserstoffperoxid enthält, um ein stabiles Bleichmittel zu erhalten.Of course, the invention is not based on the illustrated embodiment limited. Further refinements of the invention are possible without leaving the basic idea. However, it is essential that the dishwashing detergent according to the invention contains stabilized hydrogen peroxide to get a stable bleach.
